Good To Know

Q: What is the main difference between this SPST switch and a heavy-duty relay? A: This SPST switch is a manual mechanical disconnect, meaning it physically separates the battery cable, whereas a relay is an electrically controlled switch. The manual design here offers a simple, fail-safe way to sever power without relying on any electronics.

Q: Can this switch handle the full cranking current of a starter motor? A: Yes, this type of switch is rated to handle continuous high-amperage draw and momentary starter surges, but always verify the switch's continuous and intermittent amp rating against your vehicle's cranking circuit for guaranteed longevity.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
